With my fuel filler can A I provide a cylindrical tank body portion Iclosed at its lower end by the cylindrical bottom portion II'.' A

cylindrical top portion I2 is secured to the upper."

edge of the body portion III. A pressure relief valve I3 is secured tothe cylindrical top portion I2 for releasing pressure built up withinthe body portion). A metaldischarge pipe I5 extends from the uppersurface of the top portion I2 downwardly into the tank portion II] to apoint just: .abovethe bottom I I thereof. Attached to the upperend. ofthe discharge pipe I5 is a length of :flexible'hose'or tubing I6 whichmay be coiled on thetop surface of the top portion I2 as illustrated inFigures 2 and 3. The filler hose I6 is provided with a shutoff valve I'lsecured to the end thereof.

The. pump unit B is located centrally of the top portion ;I2 and iscomposed of a cylindrical base 'portion,l8. which is secured to the topportion l2 at Iil Thecylindrical cup-like member is adapted to bescrewed into the cylindrical base portion I8 and the top portion ofwhich is provided with the irregularly outlined lug receiving holes 2I.; Secured Within the cup-like member:20 is a collar 22 which isadapted to position the elongatedcylinder casing 23 together with thewasher 24. The pump unit B is further composed of the plunger 25 whichis adapted to operate within the cylinder casing 23 and will force airdownwardly and outwardly through the. valve 26 which is composed of thewasher 21, the retainer 28 and the spring 29. As pressure is directedagainst the washer 21 it moves downwardly allowing air to'be forceddownward through the opening 30 as a result of the action of the plunger25 moving downwardly in the cylindrical casing 23, As air is, forcedpast the valve 26 and intothe cylindrical tank body Ill, the pressurethen exerted on the fuel within the body portion I0 will force fuelupwardly through the discharge pipe I 5 and out of the 'hose I6 when theshutoff valve I1 is open. The plunger 25 is operated by the rod M whichis secured to the handle 32.. Secured to the rod 3I are the lugs33..which are adapted to engage within and under'the top portion 2I' ofthe cup-like member 20 by means ofthe irregular lug receiving holes2I"to secure the lid 34 to the cover portion 34". The circular coverportion 34 is secured to the upper edge of the body portion II). Thehandle 32 is further secured to the lid 34. The handle 32 is turnedslightly to disengage the lugs 33 from the irregular receiving holes 2|so that the handle 32 together with the lid 34 may bedrawn upwardly,thereby allowing the plunger 25 'to move upwardly within the casing 23.r

' The pressure relief valve I3 is composedof the vertical rod 35 at thetop of which is secured the cap 36 which operates to move upwardly anddownwardly over the cylinder 31 against the action of the spring 38. Asthe cap 36 is moved downwardly the washer valve 39 and retainer 40 alsomove downwardly, allowing air pressure which may have been built upwithin the body portion II) to escape through the valve. A hole oraperture 4| ispformed in the cover 34 in such 4 V a position that thepressure relief valve I3 will extend therethrough for easy operation.When the lid 34 is closed upon the aperture 43 of the cover 34, theclosed compartment 42 is formed wherein the -fil;ler hose Stored. ,v 7My device is operated in the following manner. When the lid 34 is in aclosed locked position thehandle 32 is grasped by the user and turnedslightly in one direction or the other to disengage the'lugs 33. As aresult the lid may be moved upwardly and downwardly which allows theplunger 25 to build up pressure within the body portion III by moyingthe handle 32 in an up-and-down movement. As pressure is built up easilyand readily within the body-portion- I0, any liquid therein'will tend tobe driven upwardly into the-discharge pipe I5 and outwardly through the'filler hose I6 to the valve I1. The filler hose "IIi'is convenientlycoiled in the compartment 42 formed .by the top portion.- I2, the cover34',- and the lid 34. The filler hose IIi is" uncoiled and placed in acontainer which is desired to be filled. When the container is filled,the liquid or fuel remaining in the filler hose-I6 may be drawn back:into the-body. portion I0 of my fuel filler can by releasing thepressure therein by means ofthevalve I30 1 My fuel filler can A isfilled with liquid by engaging the lugs.33 under the portion 2| andturning counter-clockwise thereby removing the cup-like member '20together with the pump unitB.

.My device may alsopbe u'sedfo'r siphoning fuel or liquid from acontainer into'the bod portion .IIl ofmy fuel filler can by forcing fuelinto the filler hose I6 inthe manner-above described and inserting theend of the filler hose 115 into 'thefuel .to be siphoned with the valveI! open.

The pressure relief valveI 3 is then depressed and opened, allowing theJfuel or liquid in'the filler hose I6 to return'to thezwfiller can A,drawing with it the liquid or fuel-in the containerwhich is desired to.be emptied into my:fue1'filler;can.'i

In Figure, '7 I-have illustrated a form-ofa pressure; relief :valve 0..The valve; C is operated when the lid 34 iszmoved downwardly and lockedin'position, the outer portionof the lid contacting therod .45 which isin turn pushed downwardly opening the valve proper:,46. The valveCissecured to. the top portion .12 :with the,-.rod,45 extending through asmall hole formed ini the cover portion 34'. Thuswhen sufiicientair'pressure is built up within the filler canA, the lid 34 is closedand locked inpositionthereby opening the valvec allowing; the fuel inthe filler hose. to tu n t the fille ca as'a re u t of the pressure onthe tollsurface of the fuel'being relieved by meanslof the operation ofthe valve 0.

In Figure ,8 I haveillustrated a formof a pressure relief valve Dwhichiis positioned on'the' i 0 the fill pan -a d h s exe tends upwardthrough an aperture 41 formedin the lid portioh 34.- The valvel he ad 48is p hibited from .niakingia completeliseal by a. small channel Pdr 'n.9 w i h ellewsa s al m unt of airto escapesalthough thevalve head is onits seat. The cvalve head 48 is opened "com; pletely by pushing downwardon the-button 50 when it is desired toreliev ethe air pressure on thefuel in thefillercanAl 7 A I In Figure 9 Ihave'illustratedaform'oftanair pressure release which embodies airaised'portion lease of air pressure at all times, but small enough in diameterto allow pressure to be built up on the fuel in the filler can. Theraised portion 5| is formed on the top portion l2.

The air relief valves in the container do not interfere with thesecuring of sufiicient air pressure to force the gasoline or liquid fuelout of the container when the pump B is operated.

A series of drain holes I2 are provided where the top portion I2 joinsthe outer wall portion ID to allow any liquid which is collected on thetop portion I2 to drain from the compartment 42. This leaves thecompartment 42 which contains the hose, dry at all times.

The shutoff valve I! may be equipped with a removable strainer screen(not illustrated in the drawings). However, this screen is of ordinaryconstruction which will prevent any foreign matter entering the gas tankof the outboard motor or the vehicle where my filler can and hose areused.
